SPECIFICATION forming part of Letters Patent No. 652,018, dated June 19,1900. Application filed February 15 1200. Serial No. 5,275. (No model.)

T0 at whom it may concern:

Be it known that I, J OHN CHARLES DUNER, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois, haveinvented a certain new and Im' proved Gate or Door, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

-door--such as is used, for example, on elevated trains-considerableroom is required for the operation of the door, and if passengers arestanding close together and near the door, upon the platform, it isfrequently nec-' together, one of the parts being hinged or pivotallymounted upon the door frame or jamb and the other provided with aprojection or roller arranged to engage a suitable guideway or slot,which may be either above or below the door, or both, so placed andconstructedthat when the entire door swings upon its main hinge theseveral parts of the door will swing upon the hinges by which they arepivoted to each other into position to close the door-opening on closingmovementof the operating means and into position to leave the openingfree and clear on opening movement of the operating means, the path ofmovement of the several parts of the door being within a confined orlimited space, as will be hereinafter more particularly described, so asto interfere-as little as possible with any person or persons who may bestanding adjacent to the door while it is being manipulated.

The operating means which I prefer to employ in connection with mypresent invention is generically the same as that forming thesubject-matter of a pending application filed by me April 29, 1899,Serial No. 714,950, but specifically embodies certain improvements,which will be hereinafter more fully described.

Referring now to the accompanying drawings, it will be seen that inFigure 1 thereof I have shown a plan section illustrating my improvedtype of door in open position, in Fig. 2 the door in closed position, inFig. 3 a side elevation designed to illustrate more clearly theoperating means and the improvements thereon, in Fig. 4 a sectionalview, on an enlarged scale, of the projection or roller upon the edge ofthe door, and in Fig. 5 a plan view of the said device.

To a frame or jamb 1 is pivotally secured a door comprising a pluralityof parts,as 2 and 3, which parts are pivotally secured together, as at4, and provided with operating means connected at 5 for opening andclosing the door, the said operating means comprising, essentially, atoggle-lever 6, a spring and check device 7, a hand-lever 8, connections9, and guide-bracket 10, all arranged and operatingsubstantially asshown in the prior application hereinabove referred to.

Upon the part 2 of the door I provide a staple or eye-bracket 11,designed when the door is in an open position to engage a hook 12,

which is pivotally mounted in a bracket 13, attached to the door-frame.To the hook 12 is secured a'rod 14, passing through a guidebracket15,which forms an abutment, against which the spring 16 acts in adirection to hold the hook or catch 12 in engaging position.

The other end of the rod 14 is formed into a loop 17, which rests abovethe guide-bracket 10 and throughwhich projects the lower end of asublever 18, which is pivoted to the handlever at 19 in position to beengaged by the will cause the part 3v to draw away from the said guidehaving a portion of its length inpost or jam-b 23 and be, as itwere,retracted clinedor ofiset. substantially as, shown at 25, toward thecenter-of. motion of the part' 2, the and" means whereby the said partsare guided part 2 meanwhile swingingabout its pivot on in opening andclosing movement by the said the are 24, the parts of the door whenfully guide, substantially as described. 40 opened occupying theposition clearly shown 2.
